CHAZ Hurricane Hazard Map

SSP Scenarios (Shared Socioeconomic Pathways) represent different future emissions trajectories:

SSP245: Moderate mitigation, ~2.7°C warming by 2100
SSP370: Medium-high emissions, ~3.6°C warming
SSP585: High emissions (fossil-fueled), ~4.4°C warming
CMIP6 Climate Models used to drive CHAZ hurricane simulations. Different models have different assumptions about physical processes. Multi-Model Mean averages all 6 models to reduce individual model biases.
Historical: Baseline conditions (1995-2014)
Mid-Century: Near-future projection (2041-2060)
Late-Century: End-of-century projection (2081-2100)
Return Period is the average time between events of this intensity. A 100-year wind speed has a 1% chance of being exceeded in any given year. Higher return periods show rarer, more extreme events.
